General Concrete Applications Projects
Predictive Model for Void Content and Strength of Pervious Concrete Pavements Installed in the Field - Field testing of pervious concrete pavements (PCP) and laboratory testing of collected specimens were used to identify a non-destructive, simple and reliable in-situ test to control the quality of PCP jobs by lightweight deflectometer testing. The results of the field testing were extended beyond quality-control purposes to obtain in-situ infiltration rates to estimate the required compaction efforts for future projects and also to estimate structural properties for layer thickness design.
A Scientific Investigation into Concrete Durability - Through a collaboration between the MIT Concrete Sustainability Hub (CSHub), Oregon State University (OSU), and the University of New Brunswick, this study will help to improve the durability of concrete pavements by improving the scientific understanding of pavement distresses, especially regarding alkali-silica reaction (ASR) and freeze-thaw (FT). Please note that this document is over 19MB in size.
Guide to Concrete Trails - More and more communities are embracing recreational trails. The Guide to Concrete Trails provides background, details and information about the entire process of installing a concrete trail. There are three versions of the Guide available, including a high-resolution PDF (please note that this version is 45 MB and may take a long time to download), a low-resolution PDF (8 MB), and a PDF optimized for viewing on a tablet (5 MB). To receive the high-resolution version of the Guide on a USB key and/or a hardcopy, please contact Jennifer LeFevre.
PavementDesigner.org - This online pavement design tool offers features and benefits never before available to the pavement design community. This resource is free of charge and was created for city, county, and consultant engineers, academia, or anyone involved in design of roadway industrial, and parking area pavements. It was created through a collaboration between the National Ready Mixed Concrete Association, the Portland Cement Association and the American Concrete Pavement Association, with co-funding provided by the RMC Research & Education Foundation. Additional resources available include a webinar recording of how to use it and a PDF of that presentation.
Guide to Concrete Overlays of Asphalt Parking Lots - This guide provides information and guidance in areas including, but not limited to, assessing the integrity of the exiting pavement, selecting project candidates, pavement design principles and design life, managing parking lot drainage, and dealing with entry evaluations of adjacent buildings. Additional Features: AutoCAD files that complement this Guide are available. Please contact contact Jennifer LeFevre for more information. A short video introducing the use of concrete overlays of asphalt parking lots may be accessed here.
Improving Specifications to Resist Frost Damage in Modern Concrete Mixtures - This report was part of a 12-state pooled fund study examining frost damage on air-entrained concrete treated with salts, including how any impact may be mitigated. The link to the study and other supporting materials is included in the project name above.
Impact of Extended Mixing Time to Discharge on Concrete Durability and Performance - Performed by the New Jersey Institute of Technology, this project examines whether the current 90-minute time limit for the use of ready mixed concrete could be extended without compromising durability and performance.
Evaluation of Chloride Limits for Reinforced Concrete - This report represents Phase A of a two-phase report and includes technical data that will support a code change that will change the limits to the basis of cementitious materials used in the ACI 318 Building Code for Structural Concrete.
ICFMA Thermal Study Summary and Test Data - This is a summary of the Insulating Concrete Form Manufacturers Association's thermal comparison study between ICF and wood/steel frame assemblies. The link includes the study summary and detailed test data.
Erosion Design Reports - The goal of these reports is to help designers assess whether the natural, compacted subgrade at a project site is adequate for long-term pavement performance or if subgrade stabilization or a subbase is required to meet design criteria.
Examination and Evaluation of ACI 347.3R-13 "Guide to Formed Concrete Surfaces" - This report was funded by the American Society of Concrete Contractors Education, Research & Development Foundation, the ACI Foundation and the RMC Research & Education Foundation.
Building Information Modeling Strategic Plan Completed - The Strategic Development Council (SDC) of the American Concrete Institute's ACI Foundation has released the Building Information Modeling (BIM) Strategic Plan. The development of the Strategic Plan was funded by the RMC Research & Education Foundation and the Charles Pankow Foundation. The Strategic Plan may be accessed here.
National Institute of Standards and Technology's Virtual Cement and Concrete Testing Laboratory Consortium- Information on the VCCTL project at NIST may be viewed here. Educational VCCTL software may be accessed here. Another resource - Modeling and Measuring the Structure and Properties of Cement-Based Materials - may be found here.
A webinar on the VCCTL and its successful application took place on June 3, 2013. You can click here to access the recorded webinar on YouTube. Dr. Vichit-Vadakan's webinar presentation may be accessed here. You may also view the panelists' presentations below:

Revised Life-365 Software Now Available for Download - The Life-365 software, information, and instructions are available for download from here (please use link included on page). The software, designed to estimate the service life and life-cycle costs of alternative concrete mixture designs proportions, life-cycle costs of alternative concrete mixture designs proportions and corrosion protection systems
P2P Initiative Resources
Improving the Reliability of Resistivity Tests of Concrete - Conducted by researchers at the National Ready Mixed Concrete Association's Laboratory, this report indicates that the measuring the resistivity of concrete is a reliable test method to predict its permeability property and potential durability. The document also includes an Addendum on the Optimal Curing/Conditioning for Resistivity Specimens. An Executive Summary is also available.
Optimizing Concrete Mixtures for Performance and Sustainability - With the research performed at NRMCA's Research Lab, this report examines how reducing or eliminating minimum cementitious materials requirements in mixtures will allow for more flexibility in achieving better performance and a more sustainable design.
Evaluation of Performance-Based Alternatives to the Durability Provisions of ACI 318 Building Codes - This project, performed at NRMCA's Laboratory, seeks to increase the implementation of performance-based specifications that will be accepted by state highway agencies and the industry. It was part of a larger pooled-fund study in the development of performance criteria for concrete that will be resistant to penetration of chlorides, cycles of freezing and thawing, and sulfate attack.
Quality Management System for Ready Mixed Concrete Companies - The QMS is a tool that will assist ready mixed concrete companies with creating their own quality plan and includes a sample plan for a fictitious RMC company.
Model Performance Spec Phase II: Guide to Specifying Concrete Performance - This guide specification was written specifically for the provisions of ACI 318-08, Building Code for Structural Concrete and is intended to address properties or requirements for ready mixed concrete based on performance. It covers requirements for concrete that are not addressed in ACI 318.
Experimental Case Study Demonstrating the Advantages of Performance Specifications - This final report outlines the results of a laboratory study designed to show the advantages of performance-based criteria over prescriptive requirements in concrete specifications.
Model Performance Spec Phase I: Preparation of a Performance-Based Specification for Cast-In-Place Concrete - Phase I of this project includes a literature review and identifies the methods for the development of a guide to specifying concrete performance.
